Question:
Which is a requirement of a site-to-site VPN?

• It requires hosts to use VPN client software to encapsulate traffic.
• It requires the placement of a VPN server at the edge of the company network.
• It requires a VPN gateway at each end of the tunnel to encrypt and decrypt traffic.
• It requires a client/server architecture.

Explanation: Site-to-site VPNs are static and are used to connect entire networks. Hosts have no knowledge of the VPN and send TCP/IP traffic to VPN gateways. The VPN gateway is responsible for encapsulating the traffic and forwarding it through the VPN tunnel to a peer gateway at the other end which decapsulates the traffic.
